Sigourney Weaver has revealed the reason why director Neill Blomkamp's planned fifth Alien movie has been delayed - original Alien director Ridley Scott and his plans for the prequel. In an event at the data center companyVMWare (viaAggressive Comix), Weaver said that the sequel to Prometheus, now titled Alien: Covenant, changed plans for Blomkamp's seperate film.

Ridley asked Neill not to make our Alien til after Prometheus 2," Weaver reportedly said. "He wanted his movie to shoot and be released first. But it’s an amazing script, and Neill and I are really excited about doing it. We’re doing other things until we can get going on that. I’d be really surprised if we didn't do it, because it’s such a great script, and we love working together. So, it’s just going to take a little bit longer to get out to you, but it’ll be worth the wait."

Blomkamp's as-yet-untitled Alien film would see Weaver reprising her role as Ellen Ripley, alongside Michael Biehn.

The director released new concept art for his Alien film, featuring a grown-up version of Newt from Aliens.
